Seoul - Yonhap

South Korea's financial regulator repeated Thursday that it will sternly deal with a recent massive data breach and overhaul measures to better protect personal information.
Last month, the Financial Services Commission (FSC) revealed that some 20 million clients' personal data, including bank account numbers, addresses and credit ratings, had been leaked from three credit card firms -- KB Kookmin, Nonghyup and Lotte.
